TYPEWRITER.

Application filed February 20, 1924. Serial No. 694,076.

do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters or figures of referencemarked therein which form a part of this specification.

This invention relates to a typewriter in which the rotation of acylindrical drum carrying in relief several rows of type, is controlledby the depression of a key of a keyboard, so as to bring the type orletter corresponding to the depressed key to the level of the paper onwhich the typing is to be done, and it relatesmore particularly to thegeneral arrangement of the various elements of the typewriter.

The angular movements of the drum are controlled by an oscillatingelement or rock ing lever which is operated by means of various leversby depressing one of the keys of the keyboard.

The oscillating lever or rocker is looked after it has turned through acertain angle by means of two tappets or stops which are brought intotwo given positions by thev depression of a key. One of the said stopsor tappets produces moreover the rotation of the rocker. c I

The part carrying the stops forms one side of a deformable verticalquadrilateral which is parallel to the front of the machine, and one ofthe stops or tappets' acts on one of the sides of a deformablehorizontal quadrilateral which is secured to the rocker so as to causeit to swing when it is moved. The said part carries two lateral tappetson the side which corresponds to the horizontal' quadrilateral, for thepurpose of deforming it, whilst a central stop is intended to limit theangular movement of the rocker in either direction.

The keys of the keyboard are arranged in series of three keys, forinstance along the I two sides of intermediate spindles, each spindlecontrolling the movements, in the two directions, of one of the partscarrying the tappets or stops which control the angular position of anoscilatingeleinent or rocker.

The drum comprises several rows of characters or type and in order. tomake itpossible to bring one of the rows to a given level, so as toallow a character or letter ofthe said row to be printed,=the drum ismoved in its axial direction on a key being lowered, by means of asystem of levers acting on the spindle of the drum.

-The inclination of the spindle carrying the drum, towards the paper forthe purpose of printing a given character or type, is controlled by anelement which at the end of its movement comes in contact with the partcarrying the tappe'ts or stops.

In order to be able to produce simultaneously the inclination of thespindle of the drum and its movement in the direction of its axis,'thetype drum is mounted on a spindle which is longitudinally adjust ablebut cannot turn, in the interior of'the hollow spindle, the angularposition of which is controlled by the depression of one or another ofthe keys.

The automatic movement of the carriage in the direction of writing, to alength corresponding to that of the character that has been justprinted, is brought about by means of a control part also operated bythe part carrying the stops, 011 itsbein'g moved, the said control partproducing by its movement the release of the spacing mechanism. Thecontrol part comprises one or more detachable elements which canberemoved permanently in order that certain of the parts carrying thetappets or stops, shall not, when moved, come in contact with the saidcontrol part; The latter is constituted by a pivoted transverse baragainst which rests, at the end of its oscillation, the part carryingthe stops, producingby its movement the release of the escapementmechanism.

The paper is carried and drivenby a device mounted on thecarriageandcomprising two pairs of cylinders driven simultaneously, between whichis arranged a detachable flat element which forms support for the paperat the moment of typing.

A construction according to the invention is illustrated by way ofexample in the accompanying drawings:

Figure 6 is a plan of the central mechanism, showing diagrammaticallythe arrangement of the stops or tappets controlling the angular positionof the type drum.

The typewriter, according to this invention is a machine of the type inwhich a cylindrical drum carrying in relief several rows ofinterchangeable printing characters or type is controlled by thedepression of a. key, for the purpose of producing the typing of thecharacter marked on the said key.

The machine comprises:

1. A key board comprising a certain number of keys 1, suitably arrangedin groups.

2. An intermediate mechanism producing the movements of the drum so asto bring the character corresponding to that marked on the depressedkey, in contact with the paper.

3. A drum mounted on a spindle which in its normal position is verticalbut can be inclined towards the paper in order to produce the impressionor striking.

This drum has formed thereon several rows of characters or type whichare arranged along the generatrices of the cylindrical drum.

4. A carriage operated by a spring acting so as to produce its automaticmovement in the direction permitting writing, the said carriage beingtemporarily held in place, in order to allow a character to be typed, byan escapement mechanism which is released immediately after the typing.This carriage may be brought back by hand, this movement producing thesetting of the said spring.

5. A paper holder which carries and drives the paper and may be operatedby hand or by the automatic line-spacing mechanism.

The mechanism which controls the movements of the drum must perform thefollowing operations;

1-. To produce the rotation of the drum to a given angle so as to bringto the level of the paper that generatrix of the drum, on which issituated the type to be printed.

2. To raise or lower the drum in its axial direction so as to bring oneof the rows of type to a given level.

8. To incline the drum towards the paper so as to bring the type inquestion in contact with the sheet and ensure the striking.

Figures 1 and 2 show the working of the various essential parts of themachine when one of the keys is depressed.

The key 1, mounted on a crank 2 parallel to the front of the machine,pivots about a supporting spindle 25 provided with a finger 3 whichturns an intermediate spindle 4 by acting on a tappet 5.

This intermediate spindle 4 acts by means of an arm 6 on a horizontalbar 7 so as to move it in a given direction. In Figures 1 and 2, themovement is such that on depressing a key 1 arranged on the right of theintermediate spindle 4, the bar 7 is moved to the left.

The bar 7 forms one side of a deformable quadrilateral 7, 8, 9 pivotedat the apices 26 and parallel to the front of themachine. The verticalarms 8 of the said quadrilateral pivot about fixed spindles 10 and arebrought back to their original position by means of springs 11 when thekey 1 rises.

The fourth side of the quadrilateral is constituted by the horizontalelement 9 which may be considered as the main element of the machine.This element carries three stops projecting upwards, namely two lateraltappets 12 and 13 and a central tappet 14.

The first function of the element 9 carrying the tappets, is to turn thecylindrical drum 24 mounted on a vertical spindle 23 and carrying thecharacters, so as to bring the generatrix of the cylinder, along whichis situated the character to be printed, opposite the paper.

To that end, the spindle 23 carries a pinion 22 which meshes with atoothed quadrant 21. The said quadrant is mounted on avertical spindle20 to the upper end of which is keyed an oscillating element or rocker18 are parallel to the front of the machine, and which oscillates to theright and to the left, thus controlling the angular movements or turningof the drum 24. In the drawings, the arms of the rocker 18 aresymmetrical relatively to its axis of rotation.

The oscillation of the rocker 18 is produced by the movement towards theleft or right of an element 15 which is secured to the rocker by meansof a pivot pin 19.

The element 15 forms one of the sides of the deformable horizontal frame15-16-17 supported by fixed pivot pins 27 and 28, the arms 17 of whichare connected to the lateral iii] moment the side 16 of the horizontalframe 1516-17 and drive the said side to the left, thus deforming'theframe. This deformation produces an oscillation of the rocker 18, andconsequently a turning of the toothed quadrant 21, until the rocker 18comes in contact with the stop 14, which limits the movement to the leftof the part 9, and consequently the locking of the rocker 18 and thetoothed quadrant 21 in a given position. The drum 24, the rotation ofwhich is controlled-by the quadrant 21, then represents opposite thepaper, the generatriX on which is situated the character which isdesired to type.

The second function of the element 9 carrying the tappets is to inclinethe spindle 23 carrying the drum 24 towards the paper in order to bringabout the typing of the character.

To that end, the part 9is provided at each end with a projection 31which strikes an element 32 arranged transversely of the ver ticalquadrilateral 78--9. The said element is supported by levers 33 whicharekeyed to a rocking spindle 34. On the same spindle. is also mounted anarm 35 which, when the spindle 34 turns, raises a rod 36 (which turnsabout'its support37. The said rod controls by means of levers 38 and 39the oscillation of a rigid frame 40 supported by spindles 41 resting inbearings 42. The said frame is in the tangent plane common to thetoothed quadrant 21 and to the pinion 22, and it is secured to thespindle 23 on which is mounted the drum 24, by means of collars Theinclination of the frame 40' brings the drum 24 towards the paper andproduces therefore the striking of the character.

It must be pointed out that the shape of the teeth of the quadrant 21and pinion 22 is such that they remain in mesh during th inclination ofthe spindle 23. i

' The said spindle is locked, and its position is ultimately correctedat the moment of typing by means of a toothed wheel .44 which itcarries, andthe teeth of which correspond to the columns of charactersmarked along the generatrices' of the drum 24, one of the said teethengaging with a fixed finger carried by the frame or bed of the machine.

Before describing the mechanism moving thedrum 24in its axial directionin order to bring to the desired level the row containtheir tappets orstops 1214 and 15. length of the parts 9 increases from the ing thecharacter to be typed, it is necessary to examine the arrangement andconstruction of the keys of the keyboard.

Iii-the construction shown in the drawings, the keys of the keyboardcomprise three different categories, namely those corresponding to smallletters, to capitals and to signs.

The drum carrying the characters, coinprises three lines, the upper line24 corresponding to the small letters which are cut on its periphery,the middle line 24 to the capitals, and the lower line 24 to the signs.

The keys are distributed in groups of three, each group being echelonedat one side, either on the right or onthe left of an lntermedlatespindle 4 controlling the movements of a deformable vertical quadri-'lateral 789 for the purposeof bringing the stops or tappets 121314carried by the said quadrilateral, into a given position to whichcorresponds a given angular move ment or turning of the drum 24. I

The intermediate spindle 4 is turned to the left to a certain angleunder the action of one of the three keys arranged on its right, and tothe right, to the same angle under the action of one of the keysarranged on its left, provided that a symmetrical rocker 18 is used, asillustrated. This angle is dilferentin the event of the shape of therocker 18 being unsymmetrical.

The movements to the left or to the right of a vertical quadrilateral78-9 are therefore controlled by two series of three keys by means of aspindle 4.

In the construction illustrated are shown. fifteen adjacent verticalquadrilaterals, fourteen of which have two lateral tappets 12 and 13 andone central stop or tappet 14, these fourteen quadrilaterals beingcontrolled by a keyboard of 14 X 6 z 84 keys.

The fifteenth quadrilateral 46 which is the one next to the rocker,carries only one central stop or tappet 14, and its movement which maybe to the right or to the left,

' produces only the movement of the said tapprevents an accidentalrotation of the rocker i in one direction, and simultaneously a suitablestop mechanism (not shown in the drawing) may be controlled by the saidquadrilateral when it is moved, for the purpose of preventing therotation of the rocker in the other direction.

Figure 6 shows diagrammatically the whole of the fifteen elements 9arranged side by side, as well as the relative position of The rocker 18towards the keyboard, in order to ensure that each part 9, at the end ofits travel, turns the transverse element 32 which controls theinclination of the drum 24, and also turns the element 111 whichcontrols the escapement of the carriage, to

one and the same angle.

The same results may be obtained with parts 9 of one and the samelength, by arranging the transverse element 32 and the element 111 at anobtuse angle to the intermediate spindle 4, instead of parallel.

The arrangement of the stops or tappets 12-13 on the parts 9 is suchthat to each final position of a given quadrilateral corresponds oneposition of the rocker 18 and therefore a given position of the drum 24which turns from 0 to approximately 180 in one direction, and from 0 toapproximately 180 in the other direction, so that it'is possible tobring to the level of the paper a portion of the rim formed by thecharacters and is shown clearly in Figure 6.

The central stops 14 are arranged in one straight line at right anglesto the front of the machine, whilst the stops 12 and 13 are arranged intwo lines symmetrical relatively to the central stops 14 and having theshape of a regular curve, the lateral stops 12 and 13 of the verticalquadrilateral adjoining the rocker 18 being the most widely spaced andthose of the quadrilateral next to the keyboard, being arranged the mostclosely together. Owing to this arrangement of the stops it is possibleto obtain a rotation of the drum which increases progressively from 0 toapproximately 180 in one direction, according as the deformable verticalquadrilaterals are successively moved in the corresponding direction,beginning with that which is next to the rocker 18, in order to finishwith that which is next to the keyboard. The same applies to therotation of the drum 24 in the other direction.

The mechanism for moving the drum in its axial direction is moreparticularly shown in Figures 35.

The three keys 1, 1 and 1 form a group arranged along one side of one ofthe inter mediate spindles 4, and are mounted by means of arms 2 onspindles 25, 25 and 25 concentric with, and independent of, each other.Each spindle carries a finger 3 which acts on a corresponding tappet 5so as to turn, as already described, the intermediate spindle 4, to agiven angle which is the same for each group of three keys.

The spindles 25 and 25 which carrv respectively a key 1 for the capitaland 1 for the sign, have moreover towards their end, a projection orfinger 50 or 51 of suitable shape which acts on a tappet 52 when thekeys 1 or 1 are depressed, so as to depress a bar 53.

The said bar 53, the length of which is approximately equal to that ofthe keyboard, has similar tappets at the level of the ends of thevarious spindles 25 carrying the keys, nevertheless, as shown in Figure3, two groups of keys may act on one and the same tappet.

The shape and the arrangement of the fingers 50 and 51 is such that thedepression of the bar may be produced by the action of a key withoutaffecting the others.

Moreover, the fingers 50 which correspond to the capitals, come incontact with their corresponding tappets 52 only after the depression ofthe key to an extent corresponding approximately to half its travel,whilst the finger 51 which correspond to the signs, constantly pressagainst their tappets and lower the bar 53 to a length twice as great asthe fingers 50.

The bar 53 is supported at its ends by rods 54 pivoted about a spindle55 to which is keyed an arm 56 which controls the rotation of abell-crank lever or cam 57 of suitable shape pivoted about the spindle49. Against the said cam 57, the bent end of the spindle 58 to which iskeyed the drum 24 constantly presses. The said spindle 58 slides,without being able to turn, in the supporting hollow spindle 23 alreadyreferred to, so that the spindle 58 and the drum 24 are able to move intheir axial direction relatively to the hollow spindle under the actionof the cam 57. The said cam is moved upwardly (Figure 4) by the loweringof the bar 53, so as to bring the drum to the desired height or levelfor allowing the typing of the capitals and of the signs. It is obviousthat the shape of the cam is such that it allows the spindle 23 to beinclined about its support 42.

The carriage 60 which rests by means of rollers 61 on the frame or bed62 of the machine, carries and drives the paper be tween two pairs ofrollers 6364 and 65 66 to which an identical circumferential speed isgiven by means of toothed wheels 67-68 and the driving wheels 69operated by hand or by the line-spacing mechanism 70.

Between the pairs of rollers is arranged a fiat element 71 on whichtakes place the striking of the character or type and which forms anabutment for the paper at the moment of typing. The said element 71 issecured to the carriage 60 by means of screws 72.

The mechanism controlling the move ments of the carriage, and thedetails of the escapement mechanism form the subject of two separateapplications filed concurrently with this application, the said devicesare therefore only described in as far as required. for the purpose ofcompleting the general description of the type writer and forfacilitating the understanding. of its working.

The automatic movementof the carriage 1n the direction permitting thetyping, is

brought about by the tension of a helical mounted on a spindle 102,owing to which the helical spring 101 is set at the same acting by handon a handle 108 arranged time.

According to this invention, the movement of the carriage to the lengthcorrespending to that of the character, in the direction allowingtyping, is produced by close to the keyboard, the said handle driving,when it is inclined, a rod 109 controlling the disengagement of theescapement, in such a manner, that in the same way as is the case inordinary typewriters, if the handle 108 is turned outwards, thedisengagement is prepared. and it is only when the handle isstraightened, that the movement of the carriagetakes place.

This action maybe produced automatically by the depression of a key, bvkey ing to the rod 109 an arm 110 which carries a horizontal rod 111arranged so that it is inclined outwards, by causing the said rod-109 toturn under the thrust of the deformable vertical quadrilateral whichcorresponds to the depressed key.

I To that end, the ends of the parts 9 carrying thetappets 12 43-14, arebent along 31, and the rod 111 is at a slightly greater distance fromthe ends 31, than the transverse element 32 above referred to. In thatway, it will be first the element 32 that contacts with the end 31 andbegins to incline,

' and it is only afterwards that the rod 111 is driven in order toprepare the disengagement of the escapement mechanism. The quadrilateralreturns then to its original posit-ion, and the automatic movement ofthe carriage takes place in the direction of the writing.

Certain keys, and more particularly those used torwriting signs ormathematical expressions, must merely do the typing, without producingany movement of the carriage. To that end, the rod 111 is made in twoparts screwed together, owing to which the length of the rod can bereduced at will in order permanently to placeit outside the field ofaction of certain quadrilaterals corresponding to the dead keys.

Belowthe transverse element 32 may also be placed a second elementacting like the rod 111, and into the said element are screwed stops ortappets the number of which corresponds to that of the verticalquadrilaterals. In order to cancel the action of some of thesequadrilaterals on the escapement mechanism, it is sufficient to removeor to unscrew the corresponding tappets.

It may be seen from the foregoing description and explanation that allthe parts of the central mechanism have always a free field of action.Their trajectories do not in-- tersect each other at any point, and inorder to bring into action one of the quadrilaterals, it is nevernecessaryto wait until that previously operated, has returned to itsoriginal position.

The return movement of the type drum towards its neutral position (Fig.6) during the typing, is thus eliminated.

The working of the apparatus is as follows:

Let it be assumed that a smallletter is to be typed. A key similar tothat marked 1 in Figure 5 is depressed.

The depression of the said key produces the rotation of the intermediatespindle 4 driving the side 7 of the vertical quadrilateral 7-89. In thatway, the tappets 12'13 and 14 are brought into a given position, drivingduring their movement the side 16 of the horizontal frame 161718. Thismovement produces an oscillation of the rocker 18, and it is stopped atthe moment when the said rocker comes in contact with the central stop14:. The movement of the rocker has produced a rotation of the drum 24and brought opposite the paper the generatrix of the drum, on which ismarked the character to be printed. p

Towardsthe end of its travel, the tappet 31 of the part 9 has come incontact first with the transverse element 32 which produces theinclination of the spindle of the drum towards the paper, and'afterwardswiththe rod 111 which controls the escapement mechanism, by pivotingrespectively with the spindles 34 and 109.

As soon as the typing of the character is done, the key is automaticallyraised by the tension of a suitable spring, the frame returns to itsoriginal position under the action of the springs 11, and the drumreturns to its first vertical position.

The carriage is moved to a length corresponding to a space and themachine is ready for typing a new character.

When it is desired to type a capital inscribed on one of the keys marked1 in Figure 5, in addition to the operations and movements produced asalready described the drum must be automatically moved in the desiredlevel the row of characters in which is to be found the capital to betyped.

In descending, the key acts simultaneously with its finger 3 on thespindle 4-, and with its finger 51 on the element 53 which controls byits descent the cam 57 which raises the drum 24- to the desired level.

The same applies to the key 1 which corresponds to a sign, the movementof the drum in the vertical direction being then twice as great.

The typewriter according to the invention is more particularly adaptedfor writing languages which have an alphabet comprising a large number fcharacters as it is the case with oriental languages.

This advantage is chiefly due to the arrangement of the verticaldeformable quadrilaterals, the number of which can be very great and oneach of which act two series of keys which move it to the right or tothe left, each series comprising a key corresponding to a character of adistinct group, and each group constituting a row of the type drum. Itmust be pointed out that the typewriter shown in the drawings is merelyan example for rendering the invention clearer.

Various modifications may be made in the various mechanisms used in theworking,

without departing from the invention.
